Description:
The Dongcheng DSS150 1020W Straight Grinder is a powerful, heavy-duty corded electric grinding tool designed for professional metal grinding, steel surface preparation, deburring and industrial maintenance applications.
Powered by a 1020W electric motor, the DSS150 delivers a 5,000 RPM no-load speed, providing rotational performance for compatible grinding and surface-finishing wheels.
The grinder supports a maximum 150mm (6-inch) wheel diameter with a 20mm wheel mounting hole, making it suitable for appropriately specified abrasive wheels and grinding accessories.
One of its key features is the Safety Guard Design, intended to provide a protective barrier around the grinding wheel when correctly installed and operated according to the manufacturer’s instructions.
Dongcheng also highlights Steady Operation, supporting controlled grinding and surface-finishing performance during suitable workshop applications.
The 150mm wheel capacity provides a larger working diameter than standard 125mm straight grinders, making it practical for metal surface preparation and larger grinding areas.
Unlike conventional die grinders that use 3mm or 6mm collets for mounted grinding points, the DSS150 features a wheel-based straight grinder configuration with a 20mm mounting hole.
With a 4.7kg net weight, the DSS150 has a substantial construction suitable for professional workshop operations.
The manufacturer lists a wrench, sleeve and carbon brush among the supplied accessories, together with colour box packaging.
The Dongcheng DSS150 1020W 150mm Straight Grinder is suitable for metal fabrication workshops, engineering maintenance, machinery repair, steel processing and industrial applications requiring a powerful 6-inch straight grinding machine.
